Conduits 276, 286, and 296, interconnect with feed additive manifold 378. Spray assembly 398 is attached to one end of feed additive manifold 378. FIG. 8 depicts an embodiment of spray assembly 398. Turning to FIG. 8, in certain embodiments, spray assembly 398 comprises main input 360 and sub inputs 362A, 362B, and 362C. In such embodiments, a feed additive may be mixed with water or one or more other liquids or solids within spray assembly 398 and are sprayed on the feed base. In such embodiments, the feed additive may be a liquid or a solid and may be injected into an air stream and then input into to spay assembly 398 via main input 360 or one of sub inputs 362A, 362B, or 362C. Water, one or more other liquids or solids, or another additive may also input into spray assembly 398 via main input 360 or one of sub inputs 362A, 362B, or 362C. Spray assembly 398 then sprays the resulting mixture onto a base feed.

In certain embodiments, base 366 of spray assembly 398 is veined, as illustrated by veins 364A, 364B, and 364C, to assist in directing the spray of the feed additive mixture as it leaves spray assembly 398. In certain embodiments, spray assembly 398 further comprises rubber flap 368 to further direct the spray of the feed additive mixture and to spread out the feed base such that it is evenly sprayed with the feed additive mixture.

Returning to FIG. 2A, in certain embodiments, valves 274, 284, and 294, comprise computer operable proportional valves, shutoff valves, and discharge flow meters located inline with conduits 276, 286, and 296 to regulate the dispensing rate and measure the amount of feed additive composition dispersed.

In certain embodiments, valves 274, 284, and 294, each comprises a feed screw, such as and without limitation an auger as described hereinbelow, to feed or meter out the feed additive composition. In such embodiments, the rate at which the feed additive is dispensed can be adjusted by adjusting the feed screw speed. In certain embodiments, the feed screw speed comprises a rate of rotation. In certain embodiments, the feed screw speed comprises a rate of movement of a powder/particles over a defined time interval.

In certain embodiments, feed additive assemblies 270, 280, and 290 further may be mounted on one or more load cells for the purpose of feeding via loss-of-weight methods or for calibration of feed rate speed for metering of feed additives.

Referring now to FIG. 2B, in certain applications the feed additive or feed additive suspension is sprayed directly onto feed 150 as feed 150 exits the Applicants' mobile feed preparation apparatus via exit chute 236. In certain embodiments, the feed 150 in combination with one or more feed additives falls from a distal end of exit chute 236 and into a feed bunk.

Turning now to FIG. 2C, in certain embodiments, one or more of the feed additive assemblies, such as feed additive assembly 870 and feed additive assembly 880, dispense only dry feed additives. In such embodiments, Applicants' assembly 800 may comprise feed additive assembly 870, feed additive assembly 880, discharge assembly 830, funnel 819, eductor 818, discharge line 820, spray assembly 398, and controller 400.

In the illustrated embodiment of FIG. 2C, feed additive assembly 870 comprises reservoir 872, conduit 871, motor 812, auger 810, and communication link 822. Communication link 822 interconnects motor 812 and controller 400. In these embodiments, feed additive exiting reservoir 872 via conduit 871 is transported via auger 810 to funnel 819, which dispenses the feed additive into eductor 818. In certain embodiments, auger 810 is at an incline. In certain embodiments, the incline is less than 90 (ninety) degrees. In certain embodiments, the incline is less than 45 (forty-five) degrees. At certain embodiments, the incline is between 10 (ten) degrees and (forty-five) degrees. At certain embodiments, the incline is between 20 (twenty) degrees and 25 (twenty-five) degrees. As will be appreciated by one of ordinary skill in the art, by having auger 810 at an incline, Applicants assembly 800 prevents the unwanted feeding of a feed additive due to vibration or movement of Applicants' mobile feed preparation apparatus.

Similarly, feed additive assembly 880 comprises reservoir 882, conduit 881, motor 816, auger 814, and communication link 824. Communication link 824 interconnects motor 816 and controller 400. In these embodiments, feed additive exiting reservoir 882 via conduit 881 is transported via auger 814 to funnel 819, which dispenses the feed additive into eductor 818. As also with auger 810, in certain embodiments, auger 814 is at an incline. In certain embodiments, the incline is less than 90 (ninety) degrees. In certain embodiments, the incline is less than 45 (forty-five) degrees. At certain embodiments, the incline is between 10 (ten) degrees and (forty-five) degrees. At certain embodiments, the incline is between 20 (twenty) degrees and 25 (twenty-five) degrees. As will be appreciated by one of ordinary skill in the art, by having auger 810 at an incline, Applicants assembly 800 prevents the unwanted feeding of a feed additive due to vibration or movement of Applicants' mobile feed preparation apparatus.

As will be appreciated by one of ordinary skill in the art, while FIG. 2C depicts auger 810 and auger 814 transporting feed additives to funnel 819 which then dispenses into a single eductor, eductor 818, in other embodiments, auger 810 and auger 814 may transport feed to separate eductors. In such embodiments, after passing through the separate eductors, the feed additives may be combined prior to spray assembly 398. In other embodiments, the feed additives may be combined within spray assembly 398. In such embodiments, feed from a first educator may flow into, for example, one of main input 360 or sub input 362A, 362B, or 362C (FIG. 8) while feed from a second educator flows into another input 360 or sub input 362A, 362B, or 362C.

In certain embodiments, the speed and timing of auger 810 and/or auger 814 is controlled by controller 400. As will be appreciated by one of ordinary skill in the art, the amount of feed additive delivered can be determined by the rate and time interval over which auger 810 and/or auger 814 dispenses a feed additive into eductor 818. In certain embodiments, an auger speed comprises a rate of rotation. In certain embodiments, an auger speed comprises a rate of movement of a powder/particles over a defined time interval. As those skilled in the art will appreciate, an auger dispensing rate is directly proportional to an auger speed.

A pressurized carrier, being either a fluid or a gas, discharged from discharge assembly 830 enters eductor 818 via conduit 826 and transports the feed additive through discharge line 820 and spray assembly 398. Communication link 826 interconnects controller 400 and discharge assembly 830, wherein controller 400 controls the flow of a pressurized carrier from discharge assembly 830 to eductor 818 via conduit 826.

Referring now to FIG. 6, in certain embodiments, one or more of feed additive assemblies 270, 280, and/or 290, further comprises heater assembly 372, agitator assembly 374, pressurized air reservoir 376, recirculation assembly 380, and feed additive inlet assembly 390. The elements of feed additive assembly 270 illustrated in FIG. 6 may be implemented within any one of feed additive assemblies 270, 280 and/or 290 or feed additive assemblies 870 and/or 880.

In certain embodiments, heater assembly 372 comprises a heating tape. In certain embodiments, heater assembly 372 comprises liquid-filled heating tubes or lines. In certain embodiments, heater assembly 372 comprises heating tape, and/or heating tubes, disposed within a thermally insulating blanket or material. In certain embodiments, heater assembly 372 comprises an agent added to a feed additive, a feed additive composition, or a feed ingredient, where that agent depresses the freezing point of the feed additive, feed additive composition, or feed ingredient.

In the illustrated embodiment of FIG. 6, thermocouple 373 is disposed within reservoir 272. Communication link 391 interconnects thermocouple 373 and controller 400. In certain embodiments, controller 400 adjusts the heat supplied by heater assembly 372 based upon a temperature reported to controller 400 by thermocouple 373. In certain embodiments, the heat is adjusted by controller 400 adjusting the current provided to one or more heating tapes disposed within heater assembly 372.

In certain embodiments, heater assembly 372 is activated to prevent a feed additive composition disposed within reservoir 272 from solidifying in sub-freezing weather. In other embodiments, heater assembly 372 is used to reduce the viscosity of a feed additive composition disposed in reservoir 272. As those skilled in the art will appreciate, the temperature dependence of viscosity can be complicated because many factors enter into determining the viscosity of a material or a solution. However, over small temperature intervals, from about 0 degrees Celsius to about 60 degrees Celsius, plots of log (viscosity) vs. temperature in degrees Celsius are nearly linear, where viscosity is expressed in centipoise.

As an example and without limitation, in certain embodiments Applicants' feed additive composition comprises an aqueous solution/suspension/emulsion having a viscosity of between about 1 to about 5 centipoise. A feed additive composition comprising such a low viscosity is readily sprayable through spray assembly 398. However, that feed additive composition might run off/drip off a feed 150, and therefore, not be effectively administered to livestock.

A thickening agent can be added to the afore-described 1-5 centipoise aqueous feed additive composition to increase the viscosity. In certain embodiments, Applicants' feed additive composition comprises a viscosity of between about 150 to about 200 centipoise (consistency of maple syrup). Such a 150 to 200 centipoise feed additive composition adheres well to a base feed 150, however a rate of application of a 200 centipoise feed additive composition through spray assembly 398, might not be optimal. In certain embodiments, Applicants' apparatus and method heats a 200 centipoise feed additive composition to lower its viscosity. That heated feed additive composition is more readily dispensed through spray assembly 398, than is the ambient-temperature feed additive composition. When the sprayed feed additive composition contacts the ambient-temperature feed 150, the feed additive composition rapidly cools to ambient temperature and thickens, and as a result adheres well to base feed 150 to form a uniform base feed/additive composition.

In certain embodiments, one or more feed additive assemblies 270, 280, and/or 290, further comprises feed additive inlet assembly 390. In the illustrated embodiment of FIG. 6, feed additive inlet assembly comprises coupling 396 and inlet pressure sensor/gauge 399. In certain embodiments, inlet pressure sensor/gauge 399 indicates the pressure in feed additive input hose 392 is being used to convey a feed additive from an external tank into feed additive reservoir 272 via feed additive inlet assembly 390. In certain embodiments, inlet pressure sensor/gauge 399 is interconnected to controller 400 via communication link 386.

Coupling 396 can releasably mate with coupling 394 disposed on a distal end of feed additive input hose 392. In certain embodiments, coupling 394 comprises an automatic cutoff valve, wherein that cutoff valve closes if feed additive input hose 392 is pressurized and coupling 394 separates from coupling 396. In certain embodiments, a unique coupling combination 394/396 is used for each different feed additive assembly 270, 280, and 290, such that a feed additive formulated in a facility/tank external to Applicants' feed truck assembly and selected for input into feed additive assembly 270 cannot be introduced into feed additive assembly 280 or feed additive 290. Similarly, a feed additive formulated in a facility/tank external to Applicants' feed truck assembly and selected for input into feed additive assembly 280 cannot be introduced into feed additive assembly 270 or feed additive 290, and a feed additive formulated in a facility/tank external to Applicants' feed truck assembly and selected for input into feed additive assembly 290 cannot be introduced into feed additive assembly 270 or feed additive assembly 280.

In certain embodiments, feed additive assemblies 270, 280, and 290 further comprise a pump to discharge a feed additive composition from reservoirs 272, 282, and 292. In certain embodiments, feed additive reservoirs 272, 282, and 292 are pressurized such that a feed additive composition is dispensed under pressure via a spray assembly 398. In certain embodiments, mobile feed preparation apparatus further comprises a pressurized air reservoir 376, wherein that pressurized air reservoir 376 is interconnected to a feed additive reservoir, such as feed additive reservoir 272, via conduit 379 and regulator/relief valve 375. In certain embodiments, regulator/relief valve 375 is in communication with controller 400 via communication link 384. Controller 400 can cause regulator/relief valve 375 valve to release air pressure within reservoirs 272, 282, and/or 292 for feed additive refilling.

A feed additive composition that is not soluble in a liquid carrier comprises a suspension or emulsion. Such a suspension/emulsion may “settle,” or “separate,” respectively, prior to being dispensed onto a base feed. Continuously or periodically agitating/mixing such a suspension/emulsion as necessary will ensure the correct mix ratio.

In certain embodiments, feed additive assemblies 270, 280, and 290 further comprise an agitator assembly 374. In certain embodiments, agitator assembly 374 comprises a motor interconnected to a mixer disposed within reservoir 272. In certain embodiments, agitator assembly 374 comprises an ultrasonic mixing device.

In certain embodiments, a recirculation pump may be used, where the pump can be reversed or the valves redirected to force the suspension to flow through the dispensing lines to prevent the suspension from settling in the lines. In the illustrated embodiment of FIG. 6, recirculation output port is connected to recirculation input port 383 via recirculation pump 382 as necessary. Recirculation pump is interconnected to controller 400 via communication link 389. Controller 400 can activate recirculation pump 382 to circulate the contents of feed additive reservoir 272 outwardly from recirculation output port 381, through pump 382, and back into feed additive reservoir 272 via recirculation input port 383.

In certain embodiments, a pump and a series of valves is used to agitate the feed additive composition. In such embodiments a priority proportional divider valve routes the flow of the feed additive composition back into a reservoir, such as reservoir 272, 282, or 292, for agitation and the desired dispensing flow is bled off the main flow as required to dispense the feed additive composition. In other embodiments, multiple proportional valves are used, where the valves are set up to behave as a divider.

As those skilled in the art will appreciate, the viscosity of a Newtonian fluid is dependent only on temperature but not on shear rate and time. Examples of such Newtonian fluids include water, milk, sugar solutions, and mineral oil. On the other hand, the viscosity of a Non-Newtonian fluid is dependent on temperature, shear rate, and time. Many of Applicants' feed additive compositions comprise shear thinning, Non-Newtonian fluids, wherein the viscosity decreases with increased shear rate. In certain embodiments, Applicants' apparatus and method heats a feed additive composition to a temperature above the ambient temperature to modify its viscosity to optimize both sprayability and adherence to feed is described hereinabove.

As also described hereinabove, in certain embodiments Applicants' agitator assembly 374 comprises a motor interconnected to a mixer disposed within reservoir 272. In these embodiments, Applicants' apparatus and method applies a shear force to a feed additive composition to lower the viscosity of that feed additive composition, and sprays that reduced-viscosity feed additive composition onto feed 150 using spray assembly 398. In certain embodiments, Applicants' method utilizes both heat and shear rate to adjust the viscosity of a feed additive composition to optimize both sprayability and adherence of that feed additive composition.

In the illustrated embodiment of FIGS. 2A, 2B, and 3, Applicants' apparatus comprises three feed additive assemblies and in FIG. 2C, Applicants' apparatus comprises two feed additive assemblies. In other embodiments, Applicants' apparatus comprises more than three feed additive assemblies. In still other embodiments, Applicants' apparatus comprises fewer than three feed additive assemblies.

In certain embodiments, mixing assembly 210 is mounted on a weight-sensitive platform equipped with a weigh cell 252. In these embodiments, the weigh cell output is integrated over short time intervals to give a rate of flow and total flow.

In certain embodiments, measurement device 252 comprises a Doppler flow meter. Doppler flow meters emit ultrasonic signals into a flow path. To use the Doppler effect to measure flow in a pipe, one transducer transmits an ultrasonic beam into the mixing assembly 210. The movement of materials alters the frequency of the beam reflected onto a second, receiving transducer. The frequency shift is linearly proportional to the rate of flow of materials, and therefore, can be used to develop an analog or digital signal proportional to flow rate.

In certain embodiments, mixing assembly 210 or feed additive assembly 270, 280, and 290 is/are mounted on one or more damped load cells. The damped load cell reduces some of the vibrations and load cell ‘ringing’ caused by the moving vehicle and engine vibration. In certain embodiments, the damped load cell is further mounted to a bracket attached to the delivery vehicle using vibration isolation mounts or any other type of mounts to counteract vibrations caused by the moving vehicle and engine vibration. In certain embodiments, one or more accelerometers or motion detectors are mounted on mixing assembly 210 or feed additive assembly 270/280/290 or other suitable location to detect motion in one or more directions. In certain embodiments, a gyroscope is employed to monitor rotational movement and make any necessary corrections. In certain embodiments, mixing assembly 210 is further affixed to a gimbal mount to counteract the effects of motion on the scale.

In certain embodiments, measurement device 252 comprises weigh belts. In certain embodiments, measurement device 252 comprises a mass flow meter incorporating ultrasonic signals, scintillation counters, or any other type of flow measurement sensing equipment, or combination thereof. In certain embodiments, measurement device 252 comprises pressure transducers to measure weight or force.

In certain embodiments, measurement device 252 is further capable of transmitting a current scale weight to controller 400. In such embodiments, measurement device 252 may comprise a wireless communication module, such as WI-FI, and may wirelessly transmit the current scale weight to controller 400 for monitoring.

In certain embodiments, sensory information from devices such as accelerometers, gyro meters, motion detectors, etc. as previously described is used to determine whether weight measurements are accurate enough for use or sensory information can be used to correct weight measurements for feed additives or for the feed container 110 where the feed container 110 is mounted on load cells. In such embodiments, controller 400 may use the sensory information to determine the mass of the amount distributed. In other such embodiments, controller 400 uses weight calculation equations created using regression analysis techniques to produce one or more regression equations. In other embodiments, controller 400 uses artificial intelligence techniques to correct the scale weight received. These correction techniques also apply to weight measurements taken in other locations, for example, in the previously described embodiment where the feed additive assembly 270/280/290 is mounted on one or more load cells or in the case where feed container 110 is mounted on load cells.

In the illustrated embodiment of FIG. 2A, mixing assembly 210 is further mounted on a weight-sensitive platform equipped with a weigh cells 254, 256, and 258. In these embodiments, each weigh cell output is integrated over short time intervals to give a rate of flow and total flow.

In certain embodiments, weigh cells 254, 256, and 258 comprise Doppler flow meters. Doppler flow meters emit ultrasonic signals into a flow path. To use the Doppler effect to measure flow in a pipe, one transducer transmits an ultrasonic beam into the mixing assembly 210. The movement of materials alters the frequency of the beam reflected onto a second, receiving transducer. The frequency shift is linearly proportional to the rate of flow of materials, and therefore, can be used to develop an analog or digital signal proportional to flow rate.

In certain embodiments, a base feed 150, or partial base feed 150 with a high concentration of one or more feed additives is included for subsequent blending with base feed 150 without a feed additive or one with lower concentration of a feed additive, or a combination thereof to produce the required feed additive concentration.

In the illustrated embodiment of FIG. 7A, container 702 is interconnected with load cell 704 for inventory purposes, calibrating a metering device, or for feeding an ingredient using loss of weight techniques. In certain embodiments, load cell 704 is secured to a supporting frame.

In the illustrated embodiment of FIG. 7A, discharge gate 706 is mounted at the discharge opening of container 702. When discharge gate 706 is opened, feed additive from container 702 is added to liquid suspension mixing tank 708, having a carrier 709 disposed therein. In certain embodiments, discharge gate is automatically operable.

In certain embodiments, container 702 and discharge gate 706 are located above mixing tank 708 such that the feed additive can be gravity fed into mixing tank 708. In certain embodiments, the feed additive is a liquid. In such embodiments, a liquid pump may be employed to pump the liquid feed additive from container 702 into mixing tank 708. In such embodiments, a flow meter may be further employed to measure the amount of liquid feed additive pumped into mixing tank 708

In certain embodiments, prior to adding the feed additive from container 702 into mixing tank 708, a carrier is added to mixing tank 708 from a carrier container 714 attached via supply line 716. In certain embodiments where the carrier is a liquid, a flow meter, such as flow meter 720, may be used to ensure the proper amount of liquid carrier is added to mixing tank 708. In other embodiments, the carrier is measured by weight, by volumetric metering, by conveying for a period of time based at least in part on an actual or estimated flow rate, by determining weight of the feed additive used by loss in weight from container 702, by determining the increase in weight when added to a vessel either alone or along with another feed additive or feed ingredient, by volume whereby the feed additive or feed ingredient is added to a vessel of known volume or a vessel with graduations, or by determining the amount or volume using a level sensor or device using one or a multiple of devices including a photo-detection device, ultrasonic level measurement, capacitance, reflected sound device, or any other similar or dissimilar device used for such measurements, or combination thereof.

In certain embodiments, the liquid carrier comprises two or more different components. In such embodiments, each component may have its own liquid carrier container, flow meter, and supply line.

Before, during, or after, the liquid carrier is added to mixing tank 708, the feed additive from container 702 may be added to mixing tank 708 to produce the desired concentration. In certain embodiments, mixers 710 and 712 are active to ensure a proper mix of the feed additive and carrier. In certain embodiments, mixers 710 and 712 are rotating propellers, ribbon mixers, magnets, or any other form of physical mixing device, or combination thereof. In other embodiments, other means of mixing the liquid carrier with the feed additive may be employed, such as and without limitation, air or other gas blown into mixing tank 708 or a periodic or continuous recirculation of the feed additive composition.

In other embodiments, reservoirs 272, 282, and 292 (FIGS. 2A, 2B, 3), of feed additive assemblies 270, 280, and 290 (FIGS. 2A, 2B, 3), respectively, disposed in Applicants' mobile feed preparation mobile feed preparation apparatus, are specifically designed and/or constructed such that the motion of the mobile apparatus, while en route, provides sufficient agitation to mix a suspension emulsion, and/or keep the feed additive composition properly agitated.

Mixers 710 and 712 periodically agitate the feed additive composition as necessary during storage to ensure that one or more feed additives remain in suspension. In certain embodiments, the feed additive liquid suspension must be conveyed to mixing tank 708 for mixing. In certain embodiments, a feed additive liquid suspension is conveyed to a holding vessel for storage prior to loading into Applicants' mobile feed preparation mobile feed preparation apparatus. In other embodiments, a feed additive liquid suspension is loaded into Applicants' mobile feed preparation mobile feed preparation apparatus, without prior mixing or storage.

Turning to FIG. 7B, in certain embodiments, feed additive preparation station 700 further comprises weighing device 722 for weighing the amount of feed additive being added to mixing tank 708.

In other embodiments, the feed additive is measured by volumetric metering, by conveying for a period of time based at least in part on an actual or estimated flow rate, by determining weight of the feed additive used by loss in weight from container 702, by determining the increase in weight when added to a vessel either alone or along with another feed additive or feed ingredient, by volume whereby the feed additive or feed ingredient is added to a vessel of known volume or a vessel with graduations, or by determining the amount or volume using a level sensor or device using one or a multiple of devices including a photo-detection device, ultrasonic level measurement, capacitance, reflected sound device, or any other similar or dissimilar device used for such measurements, or combination thereof.

In the illustrated embodiment of FIG. 7B, where the feed additive is a dry feed additive, discharge gate 706, weighing device 722, and discharge gate 724 which may be connected by a sleeve. The sleeve is used to contain the feed additive and/or dust while the additive is fed from container 702 or being discharged from weighing device 722 and made of a flexible material to isolate the weighing device 722 from other components. In certain embodiments, the sleeve is opaque. In other embodiments, the sleeve is clear to allow viewing of the additive as it is being discharged from container 702 or weighing device 722.

Where the feed additive is a liquid feed additive, in certain embodiments a liquid feed additive concentrate is injected directly into the liquid carrier flow while refilling a feed truck. Flow meters on both the liquid feed additive concentrate and the liquid carrier may be used to ensure the proper amount of each liquid component is pumped onto the feed truck during the refilling process.

Feed additive preparation station 700 is preferably housed adjacent to a feed truck load out area, the location where a feed ration is loaded into Applicants' mobile feed preparation mobile feed preparation apparatus. As will be appreciated by one of ordinary skill in the art, the configuration of a load out area is particular to a given feedyard and may comprise one or more finished feed bins, a surge bin following a scale or mixer, or simply a scale or a mixer that dumps directly into the feed truck. Some facilities may employ a front-end loader to load the feed ingredients directly into a mixer-type feed truck.

In certain embodiments, a feed additive preparation area may contain one or more feed additive preparation systems. Additionally, in certain embodiments the feed additive preparation area contains one or more of a water source, a pressurized water storage tank with a boost pump if the flow or pressure from the inlet line is not sufficient to supply the preparation process, an air compressor, feed truck feed additive recharge lines, automation and control equipment, and bulk ingredient storage areas.

In the illustrated embodiments of FIGS. 7A and 7B, Applicants' feed additive preparation station 700 further comprises controller 726 comprising processor 728, memory 730 interconnected with processor 728 via a communication link, optional wireless communications module 732 interconnected with processor 728 via a communication link, and external devices 736 such as, but without limitation, a display, keyboard, touch screen, mouse, indicators, operator controls, etc., interconnected with processor 728 via another communication link.

As those skilled in the art will appreciate, wireless communications module 732 comprises a wireless network communication module implementing a wireless communication protocol such as, and without limitation, WI-FI, BlueTooth, ZIGBEE® (a wireless communication protocol by ZigBee Alliance Corp.) RF, or any other such wireless communication protocol.

Microcode 738, instructions 740, and database 742, are encoded in memory 730. In certain embodiments, memory 730 comprises non-volatile memory. In certain embodiments, memory 730 comprises battery backed up RAM, a magnetic hard disc assembly, an optical disk assembly, and/or electronic memory. By “electronic memory,” Applicants mean a PROM, EPROM, EEPROM, SMARTMEDIA, FLASHMEDIA, and the like.

Processor 728 uses microcode 738 and instructions 740 to operate controller 726. Processor 728 uses microcode 738, instructions 740, and database 742, to operate wireless communications module 732, peripherals 736, discharge gates 706 and 724, mixers 712 and 710, supply line 716, and discharge line 718.

In certain embodiments, controller 726 monitors the feed additive assemblies, and if the feed additive level in one or more of reservoirs 272, 282, and/or 292 (FIGS. 2A, 2B, 3), drops below a threshold value, controller 726 prepares one or more additional feed compositions. In certain embodiments, controller 726 determines an amount of the feed additive composition already prepared and waiting in mixing tank 708 and whether an additional amount needs to be prepared.

In operation, to refill a reservoir, such as reservoir 272, 282, or 292 (FIGS. 2A, 2B, 3) or such as reservoir 872 or 882 (FIG. 2C), of a feed additive assembly, such as feed additive assembly 270, 280, or 290 (FIGS. 2A, 2B, 3) or such as feed additive assembly 870 or 880 (FIG. 2C), an operator positions Applicants' mobile feed preparation mobile feed preparation apparatus, adjacent to a feed additive preparation area. In certain embodiments, a hose is employed to connect the mixing tank of each feed additive preparation station with a reservoir of a feed additive assembly on a feed truck, whereby the feed additive composition is pumped into the reservoir. In other embodiments, the feed additive composition is transferred through the hose and into the container by compressed air, vacuum, or suction. In yet other embodiments, the feed additive composition is transferred to the container by a mechanical conveyance means such as a screw conveyor. In such embodiments, the tubing can be rigid, semi-rigid, or flexible and can be either hose, tubing, pipe, or other similar structure.

As those skilled in the art will appreciate, it is important for each feed additive composition to be loaded into the proper feed additive assembly on Applicants' mobile feed preparation mobile feed preparation apparatus. In certain embodiments, to ensure that the proper interconnection is made between a mixing tank 708 in a preparation area and to the proper inlet assembly 390 (FIG. 6) on Applicants' mobile feed preparation mobile feed preparation apparatus, an inlet pressure sensor/gauge 399 (FIG. 6) monitors an increase in pressure when the delivery system is pressurized. In such embodiments, inlet pressure sensor/gauge 399 and controller 400 verify that the feed additive reservoir is about to receive a designated feed additive composition prior to opening initiating the transfer.

In certain embodiments, different feed additive compositions may be conveyed to Applicants' mobile feed preparation mobile feed preparation apparatus, using piping comprising different couplings or adaptors, or comprising different mechanical dimensions or configurations, whereby the piping, couplings, or adaptors, will only interconnect a designated feed additive assembly reservoir to a designated feed mixing tank 708, thereby mechanically preventing an incorrect transfer of a feed additive composition. In other embodiments, an incorrect transfer of a feed additive composition from mixing tank 708 to a feed additive assembly is prevented by using an electronic interlock employing technologies such as RF transmissions, RFID, wireless communication, magnetic sensors, electronic visual identification, etc.

In certain embodiments, each container of a feed additive assembly on Applicants' mobile feed preparation mobile feed preparation apparatus has a different size or shape connector which allows only a single hose, or other form of piping, from a single mixing tank 708 to interconnect. Thus, each feed additive assembly reservoir can only receive a feed additive composition from a designated mixing tank 708 in the feed additive preparation area.

In certain embodiments, controller 726 of feed additive preparation station 700 communicates with controller 400 (FIG. 4) of Applicants' mobile feed preparation mobile feed preparation apparatus. In such embodiments, wireless communications module 732 wirelessly provides to controller 400 information, such as and without limitation the type of feed additive in mixing tank 708 and the amount. Such information may be used by controller 400 to, by way of example and not limitation, allow pumping of the feed additive only into a certain feed additive assembly or to allow only a given amount of the feed additive to be transferred.

After an interconnect between a mixing tank 708 of a feed additive preparation system and a reservoir of a feed additive assembly has been established and verified, the refilling process can begin. In certain embodiments, Applicants' mobile feed preparation apparatus comprises an inlet pressure transducer and automated inlet valve inline with feed additive input hose 392 (FIG. 6). In certain embodiments, a pump on mixing tank 708 may start to pump the prepared feed additive into a feed additive assembly reservoir. Controller 400 (FIG. 4) monitors the inlet pressure transducer to ensure that a feed additive composition transfer is being made to a correct input assembly. In certain embodiments, each reservoir of a feed additive assembly, such as reservoirs 272, 282, and 292 (FIGS. 2A, 2B, 3), comprises a sensor to monitor the level of feed additive composition disposed therein. In such embodiments, controller 400 sends a command to controller 726 of feed additive preparation station 700 to stop pumping when the feed additive assembly reservoir has been filled with a designated amount of feed additive composition.

In certain embodiments, feed additive assemblies 270, 280, and 290 (FIGS. 2A, 2B, 3) may be refilled one at a time. In certain embodiments, feed additive assemblies 270, 280, and 290 may be refilled simultaneously. In certain embodiments, feed additive assemblies 270, 280, and 290 are filled to an amount less than capacity.

In certain embodiments, controller 400 (FIG. 4) communicates with controller 726 at regular intervals during the refilling process. In certain embodiments, controller 400 communicates with controller 726 continuously during the refilling process. In such embodiments, as a safety precaution, if communication is interrupted while a feed additive assembly is being refilled, the pump may be automatically disabled and an operator notified.

As will be understood by one of ordinary skill in the art, to offload the feed additive composition in reservoirs 272, 282, and 292 (FIGS. 2A, 2B, 3) of feed additive assemblies 270, 280, and 290 (FIGS. 2A, 2B, 3) respectively, the process described above can be reversed. In certain embodiments, feed additive preparation station 700 further comprises a pressure transducer and a valve to facilitate the offloading of the feed additive composition using the correct hose.

In certain embodiments, prior to delivering feed, feed additive assemblies 270, 280, and 290 (FIGS. 2A and 2B) are calibrated using a loss of weight method while Applicants' mobile feed preparation mobile feed preparation apparatus is stationary to provide stable weight readings. In such embodiments, the distribution rate at which each assembly dispenses a feed additive at various feeding speeds can be calculated by determining a loss of weight of reservoirs 272, 283, and 292 (FIGS. 2A, 2B, 3) respectively, over known time intervals. Thus, during delivery, feeding speeds can be varied corresponding with the delivery rate of feed 150 to incorporate feed additive(s) in the correct proportion. The amount of a feed additive dispensed can be determined using the distribution rate and the length of time over which the feed was dispensed. Further, the amount of feed dispensed may additionally be determined by calculating a difference in weight of reservoirs 272, 282, and 292 just prior and subsequent to dispensing.

In operation, an operator positions Applicants' mobile feed preparation mobile feed preparation apparatus adjacent to a designated feeding site.

Applicants' mobile feed preparation apparatus is used to deliver pre-determined feed formulations to various feed bunks, wherein the feed formulation delivered to each bunk may vary. In certain embodiments, controller 400 verifies the feed bunk to be fill with a feed ration using GPS module 430 and the feeding site location recited in feed delivery database 426. GPS module 430, using optional antenna 432, determines the actual location of mobile feed preparation apparatus and compares that actual location to the location for the selected feed bunk recited in feed delivery database 426. In certain embodiments, controller 400 verifies by receiving a wireless communication from a feed bunk capable of sending wireless RFID communications. In such embodiments, controller 400 verifies the delivery location using RFID module 440, wherein module 440 emits an interrogating signal and receives using antenna 442 a response signal identifying the adjacent feed bunk.

In certain embodiments, the method compares the actual feeding site location with the designated feeding site location recited in feed delivery database 426. If the actual feeding site location differs from the designated feeding site location, the method generates a Location Alert. The Location Alert is added to feed delivery database 426. In certain embodiments, controller 400 provides the Location Alert to a central feed lot server using wireless communications module 450 and antenna 452, and/or to a display device.

In certain embodiments, the method further comprises managing multiple feed ration types for a single load of feed. In such embodiments, controller 400 may store in feed delivery database 426 one or more feed delivery routes and feed ration types. In such embodiments, controller 400 evaluates the feed ration formulations in feed additive and ration formulation database 427 for each feed ration and may determine a common subformulation. By way of example and not limitation, a common Ration A may be used to formulate several other rations by the addition of various feed additives. Thus, by way of example and not limitation, Ration B may be formulated from Ration A by adding Feed Additive B to Ration A. Alternatively, Ration C may be formulated by adding Feed Additive C to Ration A. A third ration, Ration D, may be further formulated by adding both Feed Additives B and C to Ration A. In such embodiments, controller 400 uses the information in feed additive and ration formulation database 427 to produce Rations A, B, C, and D for the respective delivery locations specified in feed delivery database 426 by operating feed additive assemblies 270, 280, and/or 290 (FIGS. 2A, 2B, 3) to combine appropriate amounts of Feed Additives B and C with Ration A according to the formulations specified in feed additive and ration formulation database 427. As this example illustrates, and will be appreciated by one of ordinary skill in the art, different feed rations can be delivered to locations specified in feed delivery database 426 from the same load of feed 150 (Ration A in this example) by incorporation of one or more feed additives in the proper proportions as specified in feed additive and ration formulation database 427 and at the proper time during the feed delivery process.

As will be appreciated by one of ordinary skill in the art, feed ration types having different concentrations of the same additive may be delivered in a single load. By way of example and not limitation, Applicants' mobile feed preparation apparatus may deliver both Ration E and Ration F using the same load of feed. Ration E may comprise a base feed mixed with 0.1% (wt./wt.) of Feed Additive E, while Ration F may comprise the base feed mixed with 0.05% (wt./wt.) of Feed Additive E. When delivering Ration E and Ration F, Applicants' mobile feed preparation apparatus may separately produce Rations E and F or may use Ration E to produce Ration F. By way of example and not limitation, in certain embodiments controller 400 operates feed additive assembly 270, wherein reservoir 272 contains Additive E, to combine appropriate an appropriate amount of Feed Additive E with a base feed to make Ration E. Controller 400 may subsequently make Ration E by operating feed additive assembly 270 to combine the appropriate amount of Feed Additive E with the base feed. Alternatively, controller 400 may operate feed additive assembly 270 to produce Feed Additive E and then, where reservoir 282 of feed additive assembly 280 also contains Additive E, operate feed additive assembly 280 to add an additional amount of Feed Additive E to make Ration F.

As will further be appreciated, Applicants' mobile feed preparation apparatus may deliver a feed ration type comprising one or more feed ration additives and no base feed. By way of example and not limitation, Ration G may comprise only Feed Additive G. In such an embodiment, controller 400 may operate feed additive assembly 270, where reservoir 272 contains Feed Additive G, to release an amount of Feed Additive G, which is then deposited in feed bunk 170 (FIG. 1C). In certain embodiments, this may be done alter the concentration or type of the feed ration currently in feed bunk 170. In such embodiments, controller 400 may use feed delivery database 426 to identify the existing feed ration type in feed bunk 170 and ration formulation database 427 to determine the amounts and/or types of additional feed additives to dispense to achieve the desired concentration or feed ration type. By way of example and not limitation, Ration F may have been delivered to feed bunk 170 at time A and a record of the delivery stored in feed delivery database 426. Controller 400 may then use ration formulation database 427 to determine the correct additives to dispense to Ration F, already located in feed bunk 170, to change Ration F to Ration G.

In certain embodiments, data stored in feed additive and ration formulation database 427 and feed delivery database 426 may be exchanged with a central feed lot server using wireless communication module 450 and wireless communication antenna 452. In certain embodiments, controller 400 periodically receives from a central feed lot server wireless updates to the feed delivery schedule to reflect changes in circumstances, such as and without limitation, arrival of new cattle or the movement of cattle from one feeding location to another. In such embodiments, controller 400 may display instructions informing the vehicle operator of the modified schedule. In certain embodiments, the vehicle operator may change the delivery order specified by the schedule due to special circumstances, such as, and without limitation, an obstruction in the delivery route. In certain embodiments, feeding results information stored in feed delivery database 426 may be transmitted to a central feed lot server.

In the illustrated embodiment of FIG. 5, feed delivery database 426 comprises (N) formulations. Referring now to FIGS. 2, 4, and 5, in the illustrated embodiment of FIG. 5, feed delivery database 426 recites that, for example, a pre-set quantity of 1000 pounds of feed 150 are targeted for delivery to the North Feed Bunk. Feed delivery database 426 further recites that, for example, 950 pounds were actually delivered to the North Feed Bunk.

Processor 410 enters the actual delivered amount into feed delivery database 426. In certain embodiments, the actual weight of feed delivered is wirelessly provided to a central feed lot server using wireless communications module 450 and antenna 452, and/or to a display device. Further in the illustrated embodiment feed delivery database 426 in FIG. 5, the nominal delivery window for delivery of base feed to the North Feed Bunk is, for example, +/− ten percent (10%). Because the actual amount delivered, i.e. 950 pounds, is within the pre-determined nominal window of 900 pounds to 1100 pounds, no alert was generated with respect to the amount of base feed delivered to the North Feed Bunk.

In certain embodiments, to stop the discharge of feed to a feed bunk, the operator signals controller 400 to cease delivery. In certain embodiments, controller 400 uses statistical information to determine the amount of base feed that will continue to be dispensed subsequent to the shutdown of the feed conveyor to regulate the remaining flow of feed additive.

Referring now to FIG. 3, in certain embodiments, after a feed additive is delivered via feed additive assembly 270, conduit 276, feed additive manifold 378, and spray assembly 398 are flushed. Similarly, in certain embodiments, after a feed additive is delivered, conduit 286 and/or conduit 296 are flushed. In such embodiments, conduit 271, 281, and/or 291 are connected via conduits 310, 320, and 330, respectively to discharge assembly 301, which is further connected to controller 400.

In certain embodiments, controller 400 operates discharge assembly 301 to inject pressurized air or other gas into conduits 271, 281, and 291 to flush any remaining feed additive in conduits, 276, 286, and/or 296, feed additive manifold 378, and spray assembly 398. In such embodiments, discharge assembly 301 comprises an air compressor. In other such embodiments, discharge assembly 301 comprises a pressurized vessel having pressurized air or other gas therein.

In certain embodiments, controller 400 operates discharge assembly 301 to inject pressurized water or other fluid through conduits 310, 330, and 320 to flush any remaining feed additive in conduits, 276, 286, and/or 296 respectively, feed additive manifold 378, and spray assembly 398. In such embodiments, discharge assembly 301 comprises a reservoir having water or other fluid stored therein. In certain such embodiments, the reservoir is under pressure. In certain such embodiments, the reservoir comprises a piston, wherein the piston applies a force onto the fluid therein. In certain such embodiments, discharge assembly 301 further comprises a pump to exert a force on the water or other fluid within the reservoir.

In certain embodiments where discharge assembly 301 is used to flush any remaining feed additive in conduits 276, 286, and/or 296, feed additive manifold 378, and spray assembly 398, controller 400 monitors the amount of feed additive flushed as well as the position of mobile feed preparation apparatus along the feed bunk. In certain embodiments, controller 400 operates discharge assembly 301 when exit chute 236 (FIGS. 2A, 2B, and 2C) is not over a feed bunk. In other embodiments, controller 400 operates discharge assembly 301 while exit chute 236 is over a feed bunk to discharge excess feed additive into the feed bunk. In certain such embodiments, controller 400 verifies that the feed bunk the excess feed additive will be flushed into is the same feed bunk as the last feed ration was delivered to.

In certain embodiments, controller 400 causes one or more open valves 274, 284, 294, to close while Applicants' feed truck is still delivering a feed ration comprising one or more feed additives to a designated feed bunk. Based upon the length of the designated feed bunk, and based upon the forward speed of the mobile feed preparation apparatus, controller 400 calculates a time interval in which valves 274, and/or 284, and/or 294, are closed, but wherein feed additives are still draining from conduits 276, and/or 286, and/or 296, into feed additive manifold 378, and wherein feed additives resident in feed additive manifold 378 are still entering into, and being sprayed from, spray assembly 398 onto a base feed being delivered to the designated feed bunk.

Returning to FIGS. 4 and 5, in certain embodiments, while feed is being delivered to the feed bunk, controller 400 visually displays information to assist the operator in moving mobile feed preparation apparatus along the feed bunk at an appropriate speed. In certain embodiments, the information includes the amount of feed delivered or remaining to be delivered and the corresponding progress along the feed bunk traveled. In certain embodiments, such information is displayed graphically. In other such embodiments, the information is displayed numerically. In certain embodiments, controller 400 emits an audible alert indicating to the operator that the operator's speed is too fast or to slow relative to the remaining feed to be distributed and the length of the feed bunk 170 left to travel or when Applicants' mobile feed preparation apparatus is not in proper position to deliver feed to specified feed bunk 170 while feed is being discharged into feed bunk.

In certain embodiments, the position of Applicants' mobile feed preparation apparatus with respect to the feed bunk is determined using GPS module 430, using optional antenna 432. In other embodiments, the position is determined using an accelerometer. In yet other embodiments, the position is determined using one or more radio frequency devices, an ultrasonic device utilizing time of flight or Doppler shift to determine speed and/or distance traveled, or one or more photo sensitive devices to determine position or distance traveled, or any combination thereof.

Further in the illustrated embodiment feed delivery database 426 in FIGS. 4 and 5, Additive A is to be added to the base feed to give a loading of 5 weight percent. In certain embodiments, controller 400 determines the weight of Additive A to be added to the base feed using feed additive and ration formulation database 427. Controller 400 opens valve 274, thereby causing Additive A to flow from reservoir 272, through valve 274, through conduit 276, and into the auger assembly 210 (FIG. 2A). Measurement device 254 determines the actual amount of Additive A added to the base feed delivered to the North Feed Bunk, and provides that weight to controller 400. In certain embodiments, the actual weight of Additive A added to the base feed is wirelessly provided to a central feed lot server using wireless communications module 450 and antenna 452, and/or to a display device.

In certain embodiments, controller 400 calculates a weight percent loading of Additive A in the base feed using the weights provided by measurement devices 252 and 254 (FIGS. 2A, 2B, 3). In certain embodiments, controller 400 then records the actual weight percent of Additive A in the base feed into feed delivery database 426. In certain embodiments, controller 400 further determines if the actual loading of Additive A is within the nominal window for Additive A. In certain embodiments, the actual weight percentage of Additive A in the base feed is provided wirelessly to a central feed lot server using wireless communications module 450 and antenna 452 for consideration in subsequent feedings.

Similarly, controller 400 calculates a weight percent loading of Additive B in the base feed using the weights provided by measurement devices 254 and 256 (FIGS. 2A, 2B, 3), and a weight percent loading of Additive C in the base feed using the weights provided by measurement devices 256 and 258 (FIGS. 2A, 2B, 3).

As will be appreciated by one of ordinary skill in the art, while the present discussion is presented in terms of a weight percent loading, the formulas for the various feed rations may be provided in any form with out departing from the scope of the present invention. By way of example and not limitation, a feed ration may be described in terms of grams per ton of feed. In such an embodiment, feed delivery database 426 additionally include a weight per mass measurement of each feed additive. In such an embodiment, controller 400 determines a mass of a feed additive being added based on the weight provided by measurement devices 252 and 254 (FIGS. 2A, 2B, 3).

In certain embodiments, controller 400 adjusts the rate at which Additive A, Additive B, and/or Additive C is added to the base feed based upon the actual feed delivery rate and the feed additive flow rate. In such embodiments, controller 400 adjusts the rate at which Additive A, Additive B, and/or Additive C is added to the base feed to match the actual feed delivery rate.

The nominal delivery window for Additive A at the North Feed Bunk is +/− ten percent (10%). Because the actual 3 weight percent loading of Additive A is outside the pre-determined nominal window of 4.5 weight percent to 5.5 weight percent, in certain embodiments, controller 400 generates an Additive A Alert with respect to the amount of added to the base feed delivered to the North Feed Bunk. The Additive A Alert is added to feed delivery database 426. In certain embodiments, the Additive A Alert is provided wirelessly to a central feed lot server using wireless communications module 450 and antenna 452, and/or to a display device.

Controller 400 similarly determines the loadings of additional additives, such as for example Additive B and/or Additive C, using feed delivery database 426, and opens the one or more corresponding valves, such as valves 284 and/or 294 (FIGS. 2A, 2B, 3). Weigh cells 256 and/or 258 (FIGS. 2A, 2B, 3) determine the actual weights of Additives B and C, respectively, added to the feed formulation, and provide those actual weights to controller 400. Controller 400 then calculates the actual weight percent loadings of Additives B and/or C, determines if the actual weight percent loadings fall within pre-set nominal windows, and optionally generates, records, and provides an alert for Additive B and/or Additive C if the actual loadings are not within the designated pre-set nominal windows. In certain embodiments, the Additive B Alert and/or Additive C Alert is provided wirelessly to a central feed lot server using wireless communications module 450 and antenna 452, and/or to a display device.

In certain embodiments, controller 400 updates feed additive inventory database 428 each time a feed ration is delivered. In such embodiments, once measurement device 254 determines the actual amount of an additive, for example Additive A, added to the base feed to make Ration A and provides the weight to controller 400, controller 400 updates a record in feed additive inventory database 428. In certain embodiments, the record may be the total amount of Additive A available for distribution. In other embodiments, the record may be the total amount of Additive A delivered that day, week, month, or other time interval. In other embodiments, the record may be the total amount of Ration A delivered or available for delivery. In other embodiments, the record may be any other type of inventory record. In certain embodiments, the updated feed additive inventory database 428 is then wirelessly provided to a central feed lot server using wireless communications module 450 and antenna 452, and/or to a display device. In other embodiments, the actual amount a feed additive delivered is wirelessly provided to the central feed lot server to update an inventory database maintained by the central feed lot server.

In certain embodiments, the total amount of a given feed additive, for example Additive A, distributed can be reconciled against the total amount of Additive A delivered according to an inventory database, either feed additive inventory database 428 or an inventory database maintained by the central feed lot server. In such embodiments, the remaining feed in each reservoir, such as reservoirs 272, 282, and 292 (FIGS. 2A, 2B, and 3) or reservoirs 872 and 882 (FIG. 2C), may be weighed using weigh cells 255, 257, and 259 (FIG. 2A) before and after each delivery and compared to the amount of feed delivered according to the inventory database. In certain embodiments, such reconciliation may occur after each time feed is delivered to a feed bunk, when mobile feed preparation apparatus has returned to the feedmill or central feed lot office after distributing feed rations, or at any other time interval. In certain embodiments, if the actual amount delivered is not the same as the amount of feed delivered according to the inventory database, an Incorrect Feed Delivery Alert is generated. In certain embodiments, controller 400 wirelessly provides the Incorrect Feed Delivery Alert to a central feed lot server using wireless communications module 450 and antenna 452, and/or to a display device. In certain embodiments, the Incorrect Feed Delivery Alert is an audible alert and/or a visual display alert. In certain embodiments, if there is a discrepancy, the feed bunk which received an incorrectly formulated feed ration can be identified and subsequently corrected.

As will be appreciated by one of ordinary skill in the art, by updating an inventory database, either feed additive inventory database 428 or a database maintained by the central feed lot server, with the actual amount of additive delivered after each time a feed additive is dispensed, Applicants' method is able to maintain an up-to-date, accurate inventory. Furthermore, such an up-to-date and accurate inventory database, either feed additive inventory database 428 or a database maintained by the central feed lot server, can be used as a quality control check to ensure the actual amount of inventory loss is reasonable in relation to the amount that should have been dispensed to produce a given feed ration. In certain embodiments, any discrepancy between the actual inventory loss in relation to the theoretical delivery amount for a given ration can be used as a calibration factor. By way of example and not limitation, feeding errors may occur for a number of reasons including, but not limited to, changes in bulk density, temperature influences, humidity, or product settling. In other embodiments, if there is a discrepancy, the feed bunk the associated feed ration was delivered to can be identified such that corrective action can be taken.

In certain embodiments, instructions, such as instructions 424 residing in computer readable medium 420, are executed by a processor, such as processor 410, to prepare and dispense a designated feed composition at a designated feeding site using Applicants' mobile feed preparation apparatus.

In certain embodiments, the method further includes scanning the animals within a particular location. In such embodiments, each animal has an RFID eartag capable of wirelessly sending data to a receiver identifying the animal. In such an embodiment, controller 400 using RFID module 440 receives a signal from an RFID eartag. In certain embodiments, controller 400 may then determine the approximate location of the animal by determining the location of mobile feed preparation apparatus using GPS module 430. Alternatively, the location of the animal may be included in the data received by controller 400 from the animal's eartag. In such embodiments, controller 400 verifies that the animals within a given area are in the proper pen using RFID module 440, wherein RFID module 440 emits and interrogating signal and receives, using antenna 442, a response signal from one or more eartags identifying the animals. If an animal is determined to be in an incorrect pen, controller 400 may wirelessly provide to a central feed lot server the location of the pen and identifying information for the incorrectly located animal using wireless communications module 450 and antenna 452.

In other such embodiments, controller 400 may use the identifying information received from the animal's RFID eartag to adjust the feed ration based on the identification of the animals within a given pen. In such embodiments, controller 400 verifies the identification of the animals within a pen using RFID module 440, wherein RFID module 440 emits an interrogating signal and receives, using antenna 442, a response signal from one or more eartags identifying the animals. Using feed additive and ration formulation database 427, controller 400 then determines the proper feed ration to be dispensed to the animals.

In certain embodiments, each time a feed ration is dispensed at a given feed pen, the amount dispensed and the location of mobile feed preparation apparatus is wirelessly provided to a central feed lot server using wireless communications module 450 and antenna 452, and/or to a display device, for billing purposes. In such embodiments, the location may be determined using GPS module 430. In other such embodiments, controller 400 may use wireless communications module 450 and antenna 452 to communicate with a transmitter affixed to a feed bunk or pen which transmits the location of that feed bunk or pen. In other embodiments, each pen or feed bunk is equipped with an RFID tag. In such embodiments, controller 400 verifies the identification of each pen or feed bunk using RFID module 440, wherein RFID module 440 emits an interrogating signal and receives, using antenna 442, a response signal from one or more tags identifying the pen or feed bunk.

In certain embodiments, the amount and location of the feed delivery is used by the central server to generate invoices to customers who have cattle housed in the feed yard. In such embodiments, an invoice is generated by the central server for the amount of rations delivered to the customer's cattle. In certain embodiments, different feed additives, and therefore feed ration types, are provided at different costs. In such embodiments, controller 400 additionally wirelessly provides to the central feed lot server the type of feed ration delivered using wireless communications module 450 and antenna 452. In such embodiments, an invoice is generated by the central server for the type of feed rations delivered as well as the amount. In certain embodiments, controller 400 may wirelessly provide the central server the type of feed additive dispensed either instead of or in addition to the feed ration type. In such embodiments, an invoice generated by the central server for the type of feed additive dispensed.

In certain embodiments, delivery of feed rations to different locations within the feed yard are associated with different costs. In such embodiments, the central server uses the amount and location of the feed delivery provided by controller 400 to generate an invoice that includes location-specific fees or discounts. In certain embodiments, various customers may be charged differently for the feeding of cattle. In such embodiments, the central server may use the location and feed amount provided by controller 400 to generate an invoice which includes customer-specific fees or discounts. In other such embodiments, controller 400 verifies the owner of the cattle being fed and wirelessly provides the identity to the central feed lot server. In such embodiments, controller 400 verifies the identification of the owner using RFID module 440, wherein RFID module 440 emits an interrogating signal and receives, using antenna 442, a response signal from one or more RFID tags on the pen or feed bunk identifying the owner of the cattle being feed.

In certain embodiments, controller 400 determines a price for the feed ration dispensed. In such embodiments, controller 400 uses feed cost database 429 to determine a cost for the feed ration delivered. In other such embodiments, controller 400 uses feed cost database 429 to determine a cost for the feed additive used to formulate the feed ration delivered. In certain embodiments, controller 400 uses feed cost database 429 to generate an invoice for the cost of the feed additive and/or feed ration delivered. In certain embodiments, controller 400 wirelessly provides the cost and/or invoice of the feed ration and/or feed additive to a central feed lot server using wireless communications module 450 and antenna 452, and/or to a display device.
